Northland's local body leaders are backing growing anger over new electricity price guidelines that will charge the region more for transmission.
The three mayors as well as chair of the Northland Regional Council are calling for the Electricity Authority's Transmission Pricing Methodogy (TPM) to be scrapped immediately and for the government to intervene in the electricity market.
Northland lines companies Northpower and Top Energy, Federated Farmers, and numerous community groups have made similar calls.
Under the authority's guidelines released about two weeks ago, each household in Whangārei and Kaipara will pay an extra $24 a year and those in the Far North district an additional $43 in transmission charges.
Energy Minister Megan Woods has not ruled out a government intervention into the electricity market, saying she was seeking advice on the matter.
